Practice, practice, practice. sum convergence of u/ (u^2+1) for u=1 to infinity. ∫ sin x dx = – cos x + C.hsilgnE nialp gnisu largetni na rof ksa ot woh gnitartsulli selpmaxe emos era ereH . Integration By Parts \int \:uv'=uv-\int \:u'v.Integration, the process of computing an integral, is one of the two fundamental operations of calculus, the other being differentiation. Derivatives Derivative Applications Limits Integrals Integral Applications Integral Approximation Series ODE Multivariable Calculus Laplace Transform Taylor/Maclaurin Series Fourier Series Fourier Transform. The integral of a function gives the area under the curve of the function. See details. Ex 7. Natural Language. \int xsin (x^{2})dx. Type in any integral to get the solution, steps and graph integrate x^2 dx. {x^{2}}dx.

 Now calculate that at 1, and 2: At x=1: ∫ 2x dx = 1 2 + C; At x=2: ∫ 2x dx = 2 2 + C; Subtract:
